Does anyone know if you can change from an RK to a TK? I'm lvl 34 RK and I want to be a TK... any info that anyone has on this subject would be very helpfull, thanks!

How to change:

1. Talk to Crean.
   
2. Unlearn your subclass.
   
3. Go to the Master Knight.
   
4. Learn the TK subclass.
   

Warning: You will loose any skill points you invested into skills. So either take the loss which is not too severe at your level or use a Class Skill Points Reset Card from the Item Mall (850 AP).

If you got to go TK, then what i would do is start a new toon. With Elizabeth's buff, you can sp farm and get your skills faster now. When your new TK hits level 25 and advances he can borrow the armor from your RK now.

You go to Crean, change your class, and LOSE the sp and you will find that sp farming is a lot harder at higher levels. So you will have to suck it up and start a new toon. That is what I would suggest.

You could buy a reset card if you are rich now. lol Not me.

I don't know many people who would consider lvl 34 to be a "high level". SP farming in the 30's is fairly quick as far as SP farming goes.
